- '5 State of Louisiana, have invented certain 'new .anduseful Improvements in Refrigerating Apparatus, of which the following is,

gears, said bevel gear K being on a shaft a specification. g

-This invent1on relates to, refrigeration apio! paratus, in which a coil of pipes is employed through 'which a refrigerantis cau-sed to circulate. i A.

The invention has for is object. to provide a simple, inexpensive and highly efficient apparatus of the kind'stated,` and to this end it consists ina novel combination and arrangement of parts to be hereinafter described and' claimed.

In order that the invention may be fully understood, reference is had to the accompanying drawings in' which- Figure A1 is a vertical section of the apparatus; Fig. 2 is a vertical section of a portion of a mixing or churning element; Fig. 3

is an elevation of a drive shaft; Fig. 4f is a A section of another positionof the mixing or churning element, and Fig. 5 is a section on the line 5 5 of Fig. l'.

Referringv specifically to the drawings, "V` .30 denotes the refrigerator chamber. Inthe 'top of this chamber is an opening'in which 'ismounted a cylindrical tank or container A which extends'down into the ,chamber and has` at its lower end a contracted por- .35 tion a communicating with the inlet of a centrifugal pump Gr mounted on the floor of the chamber.

In the container VA works av churning or mixing mechanism comprising a cylindrical a dasher consisting of blades D carried by a tubular shaft U. rfhe outei1 surface of the casing B is also armed with das'herV blades C, and the wall of s aid .casing has perforations O. At'the center ofthe topQJ of the casing B is a bearing R- through which. the dasher shaft U passes. The opening in in which the'container A seats has a clo sure lowhich also serves as a closure for the extends down to the pump G with which latter if. han n driving connection. The shaft Specification of Letters atent. 'l

the top of the chamber V,

The closure. has a F projects from the-upper end of the dasher shaft il, and on said end of the shaft U and the corresponding end ,of the shaftFv are fast bevel gears K and 72, respectively.

Through the center of the first-mentioned one of said' gears the shaft F loosel'y passes. A bevel gear K meshes with both of these the bevel gearing hereinbefore describedthese shafts rotate in opposite' directions.

.A driving connection` between the shaft F and the casing B is provided bya suitable coupling T. Onthe shaftvF is also fast a Collar S which supports the lower end of the dasher shaft U. ln the center of the bottom of the casing B is an opening P to accommodate the shaft F, said opening be* ing large enough to allow the collar S to clear the same when the parts are assembled.

in the container A, a'short distance beneath the casing B, is a screen E havinga bearing o at the center for the shaft F.

In'the chamber V, at vthe bottom thereof, is mounted a tank Hwhich is connected to 'the outlet of the pump G by a conduit h.

To this tank is also connected one end of a connected yto the container A." The conduit k is provided with a drain valve l, and the 4coil J has an overflow pipe X at the top.-

In operation, the casingB is filled with crushed ice,salt, sal soda. muriate of ammonia,

or 'other refrigerants. The space between Vthe 'casing B and the container'A is also filled with a refrigerant. The solution or brine passes through the screen E and down the contracted portion a of the container, and ,upon entering the casing of the pump G it is forced through the conduit It into the tank H, from which latterit enters the coil J and circulates,through-,the same back into the container A.. The dasher blades C and D turn in. opposite directions and thoroughly agitate'thejbrine. The screen E prevents solid matter from reaching the pump.

By the apparatus hereinbefore described, a very low temperature can be produced in a short time andvfat a small eiipense. During business hours when the chamber V is being frequently op d the temperature c an be {eeping' the apparatus 1n opkept down by eration, main taining practically the same rammen oct. 5, i915., i Application filed July 13, 191e.
